Cohorting

An important strategy to limit exposure is called cohorting. It involves dividing students and teachers into distinct groups (cohorts or pods) that stay together throughout an entire school day during in-person classroom instruction.

An important strategy to limit exposure is called cohorting.

An important cohorting policy limits the mixing between groups so that there is minimal or no interaction between cohorts.

Alternating Schedule

Alternate the days when cohorts physically attend school. For example:

  • Certain grades or classrooms physically attend school on Monday/Tuesday. Other grades or classrooms physically attend on Thursday/Friday (and the school is thoroughly cleaned in between, on Wednesday).
  • Some schools intentionally rotate in-person attendance weekly with one group of students attending during a week, followed by a different group the next week in rotation with thorough cleaning on the weekends.
  • Student arrival, drop-off, and pick-up time or locations can be staggered by cohort, or other protocols can be put in place to limit contact between cohorts and direct contact with parents, guardians, and caregivers as much as possible.
  • Hybrid options (in-class, virtual) can apply a cohort approach to the in-class education provided.
